Smartphone apps that use AI to assess skin lesions could help – but few people use them. In a project led by Susanne Gaube, we asked <strong>what makes people choose an AI-enabled app or a dermatologist</strong> for skin cancer screening.</p> <h4 id="what-we-did">What we did <a href="#what-we-did"></a> </h4> <p>We ran two online <strong>forced-choice conjoint experiments</strong> with participants from the United States (N = 1,591 and a replication with N = 308). Participants repeatedly chose between two screening offers that varied in provider type (AI-enabled app vs. dermatologist), costs, expertise, privacy policy, and the level of detail of the results. Afterwards, we assessed demographics, attitudes toward AI, and medical mistrust.</p> <h4 id="what-we-found">What we found <a href="#what-we-found"></a> </h4> <ul> <li>The <strong>type of provider</strong> was the most important factor: participants chose the dermatologist more often than the app.</li> <li><strong>Costs, expertise, and privacy policy</strong> also significantly influenced decisions.</li> <li>Preferences were rather consistent across age, gender, and ethnicity groups.</li> <li>People with <strong>greater medical mistrust</strong> were more inclined to choose the app.</li> <li>Trust, accuracy, and quality ratings were higher for the dermatologist – regardless of which provider was chosen.</li> </ul> <h4 id="what-this-means">What this means <a href="#what-this-means"></a> </h4> <p>AI-enabled screening apps will not replace the dermatologist in people&rsquo;s minds any time soon. Yet they may reach groups who distrust the medical system – which makes affordable, transparent, and privacy-respecting apps a potential way to close gaps in care for underserved communities.</p> <h4 id="read-the-paper">Read the paper <a href="#read-the-paper"></a> </h4> <p>Gaube, S., Biebl, I., Engelmann, M.
